INTERNAL-COMBUSTION ENGINE.

Application filed November 10', 1921; Serial no. 518,840.

To all/whom it may concern e Beitilm'ow'n that I, Eocnnn A. BIOTI'EftLcitizen otthe United States of America, re-

sidingetMenhosset; Long Island, Nassau Count Y., hove invented; snow anduseful ternal-Combustion Engine,of which the following 'is' aspecification;

' 'Myinventlon rclatesitoimprovements in internal combustion engines,and is :pe'rticug larl' useful in'such engines as use the heevier hyrocarbonsfor fuel; i

- In the aco'ompenyi drawing I have illustrated in e; single sectionalview so much of an internal "combustion engine as is nestle forv thepurpose of making clear my invention. I

" In said drawing, 1 represents the upper end ot a cylinder 2 re resentsthe head of. a piston workin in'ssi cylinder. "31's issents aninlet-vave in-the headof the'cy inder said valve heing'f preferably placedin.about the 'center'tliereof 4 is the stein of "valve? 3, thesumefbeinmounted inthe usual.

In the usual its engine comprising the aforesaidpnrts, t 'e tuel fed tothe miporizer is vaporized thereby on the suction-stroke of 2, and thevaporized ,fuel 18 conducted by the inletpipe to and througlithe around.valve .3. which :is' i then When it heav'ie Hydrocarbon such askerosene, 'is used, eat difliculty is, experienced in keeping a, of saidfuel in. the

a l t 1 ranged the lpit'ch of the valve seat and the s11 otlsuch fuel inu htiateofmist'.

the some would burn freely and thoroughly, and the aforesaid objectionswould be overcome.-

M aim is to ,rprovide means to prevent the uel from enterin the cylinderin a, solid state as 'distinguishe from a, finely divided or mistystate. I further aim to direct said tuel nto-the cylinder in such a waythat it will not tend to accumulate on the 'walls of the combustionchamber to a sufiicient extent to produce harmful; results. To that end,I so construct the valve seat, and b preference also the valve, so thatanysoli lifipid accumulating on the wells of the int "e pipe in'theregion of the valve (or upon the valve 'stem or guide) will be againgrotto up before actually entering the cylin- Referring again to thedrawing, it will be seen-thst the lower end of the'mlet pipe 1 isconstructed toprovide a trough or channel 7 surrounding, and closelyadjacent to, the valve seat proper. 8'-8-.ere smell ducts which leadfrom the channel T-to the surface of the'valve seat proper. that anyaccumulation of the liquid fuel in It now follows solid form on thewells of the intake pipe between the carburetor 6 and the valve 3 willrun down said wells and be caughtin the I From this channel the liquidwill pass through the small ducts- 8--8, which in as jets when theintake valve is the iuel escaping therefrom at t e seat will bere-atomized, or converted into a mist, by the velocity of the air passinover said seat during the suction stroke 0 the en ine.

I e referably provide on the up er side of. t e valveB an annular.channe 9 from which corresponding to. the channel 7 andducts 8respectively, the channel 95pm} duct 10 catching [my accumulation ofliquid on the valve is apparent thst prsctically allot the fuel entermgthe cylinder must necessarilyibe in a. finely divided or misty formwhich will burn freely and thoroughlyto the great advantage o theengine.7

It' will also be noted, that I have so orco-ectin face of the valve,that the directionof the'fuel as it enters the cylinder will this simpleexpedient, it

channel may, be extended smell v ducts-10'--10-, which function in amanner for-mend flows down i ins be more thereof,
